Struct RetryPolicy 

#[non_exhaustive]
pub struct RetryPolicy {
    pub max_attempts: u32,
    pub delay_ms: u64,
    pub backoff: RetryBackoff,
    pub max_delay_ms: u64,
    pub on_exhausted: StepFailureAction,
}

Retry behavior for a step command.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_attempts: u32

Maximum number of attempts, including the first execution.

delay_ms: u64

Fixed delay or initial exponential delay in milliseconds.

backoff: RetryBackoff

Delay progression. Omitted fixed policies preserve the pre-v1 history encoding exactly.

max_delay_ms: u64

Maximum exponential delay in milliseconds. Zero is canonical for a fixed policy.

on_exhausted: StepFailureAction

Action taken after the final permitted attempt fails.

Implementations

impl RetryPolicy

pub fn none() -> Self

Creates a policy that permits exactly one attempt.

pub fn fixed(max_attempts: u32, delay: Duration) -> Self

Creates a fixed-delay retry policy.

max_attempts is clamped to at least one and delays larger than u64::MAX milliseconds are saturated.

pub fn exponential( max_attempts: u32, initial_delay: Duration, maximum_delay: Duration, ) -> Self

Creates a capped exponential policy with deterministic full jitter.

The first delay is clamped to at least one millisecond, the maximum is clamped to at least the first delay, and every delay is selected from 1..=current_cap using the immutable run, step, and failed-attempt identities. Restarts therefore retain the same backoff decision without coordinating random state.

pub fn with_failure_action(self, action: StepFailureAction) -> Self

Sets the action taken after retry exhaustion.

pub fn continue_workflow_on_failure(self) -> Self

Configures replay to continue after the final step failure.
